Answer: 1848 feet per minute
<u>Step-by-step explanation:</u>
Answer:
D
Step-by-step explanation:
"The slope of AB is different than the slope of BC" the slope are on the same straight line, so this is incorrect! It doesn't matter which portion of the line you look at, the slope will always be the same.
Assuming that:
1
m
=
3.3
f
t
1m=3.3ft
We can make the conversion from feet per second to meters per second with this procedure:
(
165
f
t
s
)
(
1
m
3.3
f
t
)
=
50
m
s
(165
s
ft
)(
3.3 ft
1 m
)=50
s
m
Let
x
x be the amount of meters the parachutist will fall during 15 seconds of free fall
Having that in 1 second the parachutist falls 50 meters, we can calculate
x
x :
x
=
(
50
m
s
)
(
15
s
)
x=(50
s
m
)(15 s)
x=750 m
